[libvirt-users] Lib virt v4.x packages for Xenial

Hi Libvirt Users! Apologies in advance as I am sure this has been asked before (but I could not find it in the archives). Has anyone had any success creating .deb packages for Xenial for libvirt and libvirt-bin for v4.0 or v4.1? A quick scan of the PPA respository does not show anything this recent. Is there a fundamental issue that prevents these package files being created? If so has anyone got a primer for how best to install a recent version of libvirt and associated tools on Xenial? We have a bare-metal server we have to keep on LTS but I need to be able to run recent versions of QEMU to get access to certain NVMe model features that were only recently added... Cheers Stephen
